Nanotrees Harvest the Sun's Energy to Turn Water Into Hydrogen Fuel


Now this is interesting:

ScienceDaily (Mar. 7, 2012) — University of California, San Diego electrical engineers are building a forest of tiny nanowire trees in order to cleanly capture solar energy without using fossil fuels and harvest it for hydrogen fuel generation. Reporting in the journal Nanoscale, the team said nanowires, which are made from abundant natural materials like silicon and zinc oxide, also offer a cheap way to deliver hydrogen fuel on a mass scale.
